I have a:

Lenovo Y520-15KIBA CPU Intel i5 with GPU AMD Radeon RX560

linux kernel 4.20.47-custom (with bloobs of new firmware 1.175) DRM is 3.27.0

also kernel 4.17-generic is in the grub

I want to know how and if it is possible to setup a 10-amdgpu.conf file in a manner that my amdgpu is not showing errors like or at least give some glxgears output better than 1 FPS:

dmesg | grep amdgpu

[ 1.558902] [drm] amdgpu kernel modesetting enabled. [ 1.559324] amdgpu 0000:01:00.0: enabling device (0000 -> 0003) [ 1.598721] amdgpu 0000:01:00.0: VRAM: 2048M 0x000000F400000000 - 0x000000F47FFFFFFF (2048M used) [ 1.598724] amdgpu 0000:01:00.0: GART: 256M 0x000000FF00000000 - 0x000000FF0FFFFFFF [ 1.598959] [drm] amdgpu: 2048M of VRAM memory ready [ 1.598961] [drm] amdgpu: 3072M of GTT memory ready.

DRI_PRIME=0 | grep -B

Vendor: Intel Open Source Technology Center (0x8086) Device: Mesa DRI Intel(R) HD Graphics 630 (Kaby Lake GT2) (0x591b) Version: 18.2.8

DRI_PRIME=1 | grep -B

Vendor: X.Org (0x1002) Device: Radeon RX 560 Series (POLARIS11, DRM 3.27.0, 4.20.17-custom, LLVM 7

Testing my card with

DRI_PRIME=1 glxgears

gives me 0.7 (sic!) frames per second and causes system freeze

therefore I think the card is not working properly

i have tried 2019 April with:

  • drivers from amd ./amdgpu-install + pro on LMDE3, Linux Mint 19 ubuntu 18.04.1 18.04.2 (amd version 17.40, 18.x and 19.10) (each fresh install)
  • mesa ppa oibaf Mint 19 Ubunut 18
  • mesa ppa miguel Mint 19 (install failed) and Ubuntu 18
  • somehow I was able to run mesa 19 on ubuntu 18 did not make a difference in glxgears
  • custom kernel build 4.20. 5.0.6 5.0.8 5.0.9 LMDE3
  • rocm on linux mint19 -I always did a video group usermod *see below
  • I tried various xorg.confs
  • various vulkan installs and mesa-opencl-icd

*

sudo usermod -a -G video $LOGNAME

The standard configuration looks like:

sudo pico /usr/share/X11/xorg.conf.d/10-amdgpu.conf

Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" EndSection

and is working out. 

Section "Device"

is not working out (gives a black screen) and I want to know why. I hope to get better performance, when using "Device" and adding it to "Screen Section"

long story short: Updating to linux mint 20 Ulyana (cinnamon) helped me out of my misery.

dmesg|grep amdgpu

DRI_PRIME=1 glxgears

gives me 60 FPS as is my monitor refresh rate. Which tells me it is working fine now.
